Blair Caraway never wanted to see Adrian Galbraith again. Not after what happened between them. It took everything in his power to move on with his life, build a career, and get over his heartbreak. But when Blair receives a strange letter from Adrian, he must make a choice. Confused and curious, Blair agrees to visit Adrian at his family’s home, Garnet Hill. While Adrian is eager to reignite their relationship, Blair is initially cautious about trusting Adrian again.

As time passes, Blair begins to see things that aren’t really there—people from the past and visions of the future. His journal entries don’t line up with his memories, and he fears he’s losing his mind as he starts to fall back in love with Adrian. Visions aren’t the only thing wandering the halls of Garnet Hill. Someone has been sneaking into the Galbraith home and attempting to steal the family’s most cherished possession—The Shattered Heart, a precious gemstone from the family’s garnet mine. Together, Blair and Adrian must uncover the secret facets of Garnet Hill before they’re brought to ruin.
